19 Possible Causes for Hyperactive Deep Tendon Reflexes, Potassium Decreased

  • Hypomagnesemia

    deep tendon reflexes Chvostek's and Trousseau's signs Nystagmus Ataxia Cardiac arrhythmia Diagnostic Test Results-Laboratory Serum magnesium level is less than 1.5 mEq/L.[] These observations, coupled with the fact that both digitalis and magnesium deficiency lead to a decrease in intracellular potassium, suggested that hypomagnesemia might contribute[] A lack of magnesium inhibits reuptake of potassium, causing a decrease in intracellular potassium. This decrease in intracellular potassium results in a tachycardia .[]

  • Thyrotoxic Periodic Paralysis

    tendon reflexes Usually absent or depressed Usually absent or depressed Absent or depressed Normal and often hyperactive Severe respiratory muscle weakness Very rare Rare[] Found to have decreased potassium of 2.7 mmol/L and a decreased thyroid stimulating hormone level of 0.81.[] Studies suggest that restoration of potassium levels leads to resolution of paralysis, with potassium decreasing the time to resolution from 13 hours to six hours. 5 However[]

  • Hypocalcemia

    Manifestations include hyperactive deep tendon reflexes, chvostek's sign, muscle and abdominal cramps, and carpopedal spasm.[] […] to hypoxia and/or acidosis Cell destruction - crushing injuries, burns and hemolysis Inadequate Potassium Excretion - from decreased aldosterone related to Adrenalectomy[] Manifestations include hyperactive deep tendon reflexes, Chvostek's sign, muscle and abdominal cramps, and carpopedal spasm.[]

  • Electrolyte Imbalance

    A seriously abnormal increase in potassium ( hyperkalemia ) or decrease in potassium ( hypokalemia ) can profoundly affect the nervous system and increases the chance of irregular[] deep tendon reflexes.[] ECG changes in hypokalaemia The following ECG changes occur in chronological order as potassium levels decrease. T-waves become wider with lower amplitude.[]

  • Electrolytes Abnormal

    deep tendon reflexes, dysrhythmias, mood changes, confusion, reduced motility with anorexia, nausea, constipation and distention.[] A seriously abnormal increase in potassium ( hyperkalemia ) or decrease in potassium ( hypokalemia ) can profoundly affect the nervous system and increases the chance of irregular[] Definition Renal failure is often complicated by elevations in potassium, phosphate, and magnesium and decreases in sodium and calcium.[]

  • Low Chloride

    deep tendon reflexes - Tetany - Slow, shallow respirations - Seizures - Dysrhythmias - Coma - S/s of acid-base imbalances: hyponatremia, hypokalemia & metabolic alkalosis[] Potassium depletion decreases aldosterone release by the adrenal cortex.[] Hypochloremia Physiological alterations ECF volume contraction Intracellular acidosis Potassium depletion Increased bicarbonate production Decreased serum osmolarity Hypochloremia[]

  • Acid-Base Imbalance

    The signs and symptoms are numbness, tingling of fingers, toes, and circumoral region, positive Trousseau’s sign and Chvostek’s sign, seizures, hyperactive deep tendon reflexes[] Therefore, potassium moves out to make room for hydrogen ions and the serum potassium level increases. Why does the serum potassium level decrease in alkalosis?[] deep tendon reflexes. tetany of muscle groups.[]

  • Hypermagnesemia

    Other causes can include, but are not limited to: Addison Disease Autoimmune Chelation Therapy for metal exposure Decreased excretion of potassium from the body Eating disorders[] Signs and symptoms include muscle tremors and weakness, athetoid movements (continuous, slow, involuntary twisting/writhing movements), ataxia, and hyperactive deep tendon[] Decreased excretion of potassium from your body. Renal (kidney) failure is the most common cause of magnesium excess.[]

  • Spinocerebellar Ataxia Type 5

    Non-cerebellar signs such as facial myokimia, resting tremor, writer's cramp, impaired vibration sense and brisk deep tendon reflexes have been reported in some patients.[] […] channels, causing inhibition of deep cerebellar nuclei and decreasing cerebellar hyperexcitabililty. [4] One published study provided class I evidence for the use of riluzole[] […] voltage-dependent sodium channels, and stimulation of a G-protein-dependent signal transduction. [3] It is hypothesized that, in patients with CA, riluzole activates calcium-dependent potassium[]

  • Toxic Liver Disease

    deep tendon reflexes, and asterixis Diagnosis: Based on clinical picture rather than laboratory or imaging results Primary prophylaxis: None Treatment: Mainly consists of[] […] in potassium after vomiting or taking diuretics Several tests are used to diagnose hepatic encephalopathy.[] Hepatic Encephalopathy Overview: Variable abnormalities of neurological and psychiatric function, including insomnia, hypersomnia, irritability, confusion, disorientation, hyperactive[]
